There were no blood transfusion or serious complication in the study.Conclusions:Retroperitoneal laparoscopic operation,such as adrenalectomy,nephropexy,pelvioplasty,unroofing of renal cyst,pelvilithotomy,ureterdithotomy and spermatic vein ligation,have the advantages of minimai invasion,less blood loss and fewer complications,which is an effective and practical procedure.

后腹腔镜肾上腺瘤切除术、肾固定术、肾盂成形术、肾囊肿去顶术、肾盂或输尿管切开取石术及腹腔镜精索静脉高位结扎术具有创伤小、出血少、并发症少等优点，临床疗效可靠，实用性较强。

Methods Thirty-nine patients with oligospermia were included in the trail. Cell blocks of seminal fluid were made and were observed under light microscope. Expression of PCNA and P16, incidence of apoptosis in spermatogenic cells were detected by immunohistochemistry and in situ 3'DNA end labeling technique.

39例原因不明少精子症患者留取精液，制备细胞块切片，采用免疫组化技术观察生精细胞增殖细胞核抗原及P16的表达；采用原位3'羟基末端标记法观察生精细胞凋亡。15例正常精液作为对照。

Ninety-three patients with forty-two azoospermia and fifty-one severe oligozoospermia were recruited in present study. Y chromosome microdeletions were screened by detection of four locus SY84, SY134, SY255 and SPGY1 gene spaning the AZFa, AZFb and AZFc subregions of Y chromosome. The total incidence of Y microdeletions was 16%( 15/93 )in present study. Eight men in 42 patients with azoospermia had Y microdeletions, of whom 6 were AZFc deletion and 2 were AZFb deletion.

通过对93例男性不育（42例无精症和引例严重少精症）患者，Y染色体 SPGY基因、AZFa－SY84、AZFb－SY134和 AZFc－SY255位点缺失情况的研究，我们发现男性不育患者 Y染色体微缺失的发生率为 16％（ 5旧3人 42例无精子症患者中，有8例存在Y染色体微缺失，其中6例为AZF。

This paper has made further studies on the synergistic interaction and stability of salt tolerance between xanthan gum and other common food gums. It turns out that there is no synergistic interaction between xanthan gum and hydroxypropyl starch , CMC-Na. Xanthan gum and guar gum ,locust bean gum ,konjak flour have great synergistic interaction. If two or three of them mix with proper proportion, the stability of salt tolerance will greatly improve and the consumption is less than any other simple gum, further more, the cost will decrease a lot. So the complex thickeners have a obvious superiority and wide utilization in high salty food.

以黄原胶、羟丙基淀粉、CMC-Na、瓜尔豆胶、刺槐豆胶、魔芋精粉等为主要研究对象，系统地研究了黄原胶与其它食品胶2种或3种之间的协同增效作用及其耐盐稳定性研究结果表明黄原胶与羟丙基淀粉、CMC-Na复配无协同增效作用，黄原胶与刺槐豆胶、魔芋精粉、瓜尔豆胶有良好的协同增效作用，两者或三者按适当比例配合后，耐盐稳定性显著提高，用量比任一单一胶少，而且使用成本大幅度降低，因此复配食品胶在高盐食品中使用具有明显的优越性和广阔的应用前景
